    • PURPOSE: A method for manufacturing a semiconductor wafer is provided to improve the flatness on the back surface of the wafer by polishing the back surface of the etched wafer in order to have confidence in contamination of a total wafer and improve the productivity. CONSTITUTION: First of all, a wafer sliced with a certain thickness of 0.5 ¯ 0. 8 mm is polished keeping its diameter with 200 ¯ 300 mm. To improve the flatness and get over the damage on the surface, the wafer is supposed to be grinded with a slurry including abrasives. And then, the surface is grinded with finer abrasives one more time. Because fine cracks remain on the surface, the wafer is etched with chemical mixture solution and is heated at 700°C. To get a very flat surface of the wafer, both the front and back surfaces are grinded with abrasives which are much finer than the above under the condition on which pressure, heat and grinding temperature are precisely controlled. And then, the wafer is cleaned to remove the remained abrasives and the chemical solution on the surfaces. Consequently, as flatness of the back surface is improved, the contamination on the back surface is reduced and the productivity is improved.
    • 目的:提供一种制造半导体晶片的方法,以通过抛光蚀刻晶片的背面来提高晶片背面的平整度,以便有可能对整个晶圆的污染提高生产率。 构成:首先,将切片厚度为0.5〜0.8mm的晶片抛光,其直径为200〜300mm。 为了提高平整度并且超过表面的损伤,晶片应该用包括研磨剂的浆料进行研磨。 然后,再次用更细的磨料研磨表面。 由于细小的裂纹残留在表面上,晶片被化学混合溶液蚀刻,并在700℃下加热。 为了获得晶片的非常平坦的表面,在压力,热和研磨温度被精确控制的条件下,前表面和后表面都被研磨成比上述更细的磨料。 然后,清洁晶片以除去残留的磨料和表面上的化学溶液。 因此,由于后表面的平坦度得到改善,背面的污染降低,生产率提高。
